usb: renesas_usbhs: gadget: Do not discard queues in usb_ep_set_{halt,wedge}()

Browse source 
commit 1aae1394294cb71c6aa0bc904a94a7f2f1e75936 upstream.

The commit 97664a207b ("usb: renesas_usbhs: shrink spin lock area")
had added a usbhsg_pipe_disable() calling into
__usbhsg_ep_set_halt_wedge() accidentally. But, this driver should
not call the usbhsg_pipe_disable() because the function discards
all queues. So, this patch removes it.
